Updated July 11, 2022

A month-to-month lease addendum allows a landlord or tenant to change an existing rental agreement between the two (2) parties. The form can also work as an extension of a fixed-term agreement that is ending soon, modifying the lease into a month-to-month arrangement or as an alteration to an existing monthly rent agreement. It is not uncommon for a landlord to increase the tenant’s monthly rent when extending their lease to a monthly arrangement. If more than one tenant signed the original lease, all parties must sign the addendum in order for it to be valid.


All month-to-month agreements must be able to be terminated or amended in accordance with their State Required Notice Periods. Furthermore, landlords must give at least thirty (30) days’ notice before increasing a tenant’s rental cost.
